Ignore the first message I left, as I confused you with another correspondent.
Ok, it is a good... that it has plenty of memory.
Now I need the Service Tag which is about 7 to 9 digits of letters and numbers. That enables us to look at your entire configuration as when it was new...
We assume it worked when new and until now, so we don't know what it quit... but it could be a failure of one memory module...
We are hoping we can have you remove some of the memory so as to test the other memory... and the Service Tag helps me see what you have and how you can get to the memory.
If it is still under warranty, we want to be conscious of that as well... so as not to void the warranty.
Have you been back up and running since the crash? Can you reboot?
If you cannot, we want you to boot to <SAFE MODE> which you do by shutting down the power then restarting.
As soon as you restart and your first see anything on the screen, beginning pressing the <F8> key once every two seconds... until it boots... It will boot in a funny way and take quite a while...
When you get the choice, go to the top of the screen that lists possible startup options, and select SAFE MODE.
you can print it out what it has...
What you describe is more typical of inadequate memory in that model.
